Så når den tid kommer, hvor vi får brug for planter på Mars, vil vores grønne venner måske ikke være så forvirrede længere.

Om Tjernobyl
After the disaster, four square kilometres of pine forest in the immediate vicinity of the reactor turned ginger brown and died, earning the name of the "Red Forest".
Some animals in the worst-hit areas also died or stopped reproducing. Most domestic animals were evacuated from the exclusion zone, but horses left on an island in the Pripyat River 6 km (4 mi) from the power plant died when their thyroid glands were destroyed by radiation doses of 150–200 Sv.
Some cattle on the same island died and those that survived were stunted because of thyroid damage. The next generation appeared to be normal.
In the years since the disaster, the exclusion zone abandoned by humans has become a haven for wildlife, with nature reserves declared (Belarus) or proposed (Ukraine) for the area. Many species of wild animals and birds, which were not seen in the area prior to the disaster, are now plentiful due to the absence of humans in the area.
A robot sent into the reactor itself has returned with samples of black, melanin-rich fungi that are growing on the reactor's walls.
